the empty value for cuds in output_results.txt

[ebrahimnorouzi]

The values of cuds objects after the simulation are empty in the output_results.txt file.

Here is one example:

- Cuds object:
  uuid: 4c7756a8-5003-496c-b85c-709157e2ab90
  type: cmcl.MEAN_PARTICLE_SIZE
  superclasses: cmcl.MEAN_PARTICLE_SIZE, cmcl.PHYSICAL_QUANTITY, cuba.Class, cuba.Entity
  values: VALUE: 0.0
          UNIT:

    To Be Determined

- Cuds object:
  uuid: ba0bf9e9-5207-4057-a121-19f2e67856dc
  type: cmcl.PARTICLE_NUMBER_DENSITY
  superclasses: cmcl.PARTICLE_NUMBER_DENSITY, cmcl.PHYSICAL_QUANTITY, cuba.Class, cuba.Entity
  values: VALUE: 0.0
          UNIT:

- Cuds object:
  uuid: c3f62ba7-373e-4306-836d-d1d57355676d
  type: cmcl.PARTICLE_VOLUME_FRACTION
  superclasses: cmcl.PARTICLE_VOLUME_FRACTION, cmcl.PHYSICAL_QUANTITY, cuba.Class, cuba.Entity
  values: VALUE: 0.0
          UNIT:

Here is the output of that.

I've now run each example 3 times (from the head of the 'main' branch), and I cannot reproduce this issue. All output variables are populated with non-zero results.

If @ebrahimnorouzi cannot reproduce the issue on a subsequent try, then I will close it.

Thank you @mdhillmancmcl , you can close the issue.
The error was for the version of osp-core. I used v3.4.0-beta version before.
And there isn't any error with the latest version of osp-core.
